带curl的多个动作 [英] multiple actions with curl

问题描述

我试图用curl做两个动作：
1.登录到管理页面
2.提交一个表单（添加用户）
第一个很好但第二个显示错误不存在。
这是我的代码：

I'm trying to do two actions with curl: 1. Login into admin page 2. Submit a form (add user) The first one go fine but the second show error as not loged in. Here is my code:

$ch1 = curl_init();
$ch2 = curl_init(); 

curl_setopt($ch1, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1" );
curl_setopt($ch1, CURLOPT_COOKIEJAR, "cookie.txt");
curl_setopt($ch1, CURLOPT_COOKIEFILE, "cookie.txt");
curl_setopt($ch1, CURLOPT_URL, "http://admin.example.com/admin");
curl_setopt($ch1, CURLOPT_POST, 1);
curl_setopt($ch1, CURLOPT_POSTFIELDS, "user=admin&pass=password"); 
curl_setopt($ch1, CURLOPT_FOLLOWLOCATION, 1); // allow redirects 
curl_setopt($ch1, CURLOPT_RETURNTRANSFER,1); // return into a variable 


curl_setopt($ch2, CURLOPT_URL, "http://admin.example.com/admin/adduser");
curl_setopt($ch2, CURLOPT_POST, 1);
curl_setopt($ch2, CURLOPT_POSTFIELDS, "newu=demo&pass=password");
curl_setopt($ch2, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch2, CURLOPT_FOLLOWLOCATION, 1);

$mh = curl_multi_init();
    curl_multi_add_handle($mh, $ch1);
    curl_multi_add_handle($mh, $ch2);

    // execute all queries simultaneously, and continue when all are complete
    $running = null;
    do {
        curl_multi_exec($mh, $running);
    } while ($running);

//close the handles
curl_multi_remove_handle($mh, $ch1);
curl_multi_remove_handle($mh, $ch2);
curl_multi_close($mh);

推荐答案

您可以使用相同的cURL处理。在这种情况下使用 curl_multi_exec 的问题是每个curl句柄都有不同的选项，而 $ ch2

You can perform both of these requests using the same cURL handle. The problem in using curl_multi_exec in this case is that each curl handle has different options and $ch2 does not reference any cookies.

此外， curl_multi_exec 并行执行请求，这意味着您可以尝试在登录请求之前添加用户

Also, curl_multi_exec performs the requests in parallel which means you may try to add the user before the login request is completed or even started.

请尝试此操作，它说明了使用 $ ch 登录，然后使用它再次添加用户。如果服务器支持 keep-alive ，那么可以添加 keep-alive 头，并且相同的套接字连接重新 - 用于第二个请求。

Try this instead, it illustrates logging in using $ch, and then using it again to add the user. If the server supports keep-alive, then you can add a keep-alive header and the same socket connection is re-used for the second request.

$ch = curl_init(); 

curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1" );
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookie.txt");
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt");
curl_setopt($ch, CURLOPT_URL, "http://admin.example.com/admin");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "user=admin&pass=password"); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); // allow redirects 
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // return into a variable 

$res = curl_exec($ch);

// check $res here to see if login was successful

curl_setopt($ch, CURLOPT_URL, "http://admin.example.com/admin/adduser");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "newu=demo&pass=password");

$res = curl_exec($ch);

// check $res to see that the user was successfully created

curl_close($ch);
